[0002] Double-head labeling machine is a device specially designed for quickly and accurately applying labels on two different positions of a product. It is commonly used in the packaging industry and is suitable for labeling various products such as bottles, cans, and boxes. After labeling the bottle, it is often necessary to test whether the labeling is qualified and reject unqualified bottles.

[0003] Publication number CN221139025U discloses a rejection mechanism for a high-speed self-adhesive labeling machine. The mechanism comprises a frame, a main turntable, a transfer star wheel, and a reject star wheel, all arranged tangentially on the frame. A photoelectric detection unit is positioned above the conveying path between the main turntable and the transfer star wheel, and suction holes are provided at each station slot of the transfer star wheel and the reject star wheel. By providing suction holes at each station slot of the transfer star wheel and the reject star wheel, the mechanism utilizes the suction force exerted by the transfer star wheel or the reject star wheel on the bottles at the station slots to control the direction of movement of the bottles, thereby achieving the continuous rejection of unqualified bottles.

[0032] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: a conveying device for a double-head labeling machine, the conveying device is longitudinally arranged in the middle of a cabinet 1, and a rejection mechanism 2 is provided in the middle thereof, the conveying device includes: a mounting frame 3, a conveying structure 5 and a guide arrangement component 6;

[0033] The mounting frame 3 is fixedly mounted inside the cabinet 1 by means of bolts, and a conveying frame 4 is mounted on the top of the mounting frame 3 by means of bolts;

[0034] The conveying structure 5 is installed on the top of the conveying frame 4. The conveying structure 5 includes a feeding conveying group 501 installed at one end of the conveying frame 4 and a discharging conveying group 502 installed at the other end of the conveying frame 4;

[0035] The rejecting mechanism 2 is installed between the feeding conveying group 501 and the discharging conveying group 502.

[0036] like Figure 1-5 As shown, the guide and sorting assembly 6 is installed on the top of the conveyor frame 4, and the guide and sorting assembly 6 is used to sort and guide the bottles undergoing labeling inspection.

[0037] The guide and sorting assembly 6 includes a guide and sorting structure 601 installed at the feed end of the conveyor frame 4 and a diversion structure 602 installed at the discharge end of the conveyor frame 4. The guide and sorting structure 601 includes a first guide plate 6011 and a second guide plate 6012 installed on both sides of the conveyor frame 4 through a positioning seat, a spacing adjustment member 6013 installed on the top of the conveyor frame 4 through bolts, and a guide member 6014 installed on the top of the conveyor frame 4 through bolts.

[0038] Furthermore, the inner side of the first guide plate 6011 is convex, and the inner side of the second guide plate 6012 is concave, and an arc-shaped conveying channel 7 is formed between the first guide plate 6011 and the second guide plate 6012. A through hole 8 is opened in the middle of the second guide plate 6012, and the through hole 8 is used to discharge the overturned bottles and organize the bottle bodies for labeling inspection.

[0039] Furthermore, the spacing adjustment member 6013 includes a vertical plate 9 installed on one side of the conveying frame 4 by bolts, a spacing block 10 installed on the vertical plate 9 by screw thread engagement, and a first photoelectric detection group 11 installed on one side of the vertical plate 9. The bottle body is subjected to a secondary inspection by the first photoelectric detection group 11, and the travel trajectory of the bottle is adjusted by adjusting the distance between the two spacing blocks 10.

[0040] Furthermore, the guide member 6014 includes a side baffle 12 installed on one side of the top of the conveying frame 4 and a bottle blocking column 13 installed on the other side of the top of the conveying frame 4. A straight conveying channel 14 is formed between the side baffle 12 and the bottle blocking column 13. The straight conveying channel 14 between the side baffle 12 and the bottle blocking column 13 ensures the bottle's travel trajectory and facilitates its entry into the rejection mechanism 2. At the same time, a screw conveying mechanism can be optionally installed on the inside of the bottle blocking column 13 according to usage requirements.

[0041] Furthermore, the diversion structure 602 is installed by bolts on the pushing rack 6021 on one side of the conveying rack 4, the pushing member 6022 and the second photoelectric detection group 6023 installed on the pushing rack 6021 and the distribution hopper 6024 fixedly installed on the other side of the conveying rack 4. The number of bottles is detected by the second photoelectric detection group 6023. If the number per unit time is too large, the cylinder and the pushing block on the pushing member 6022 push the bottles into the distribution hopper 6024 to complete the diversion work.

[0042] Furthermore, the feed conveying group 501 includes a first gear group 5011 rotatably installed between the conveying frames 4 and a first chain belt 5012 installed between the conveying frames 4 through a rotating shaft.

[0043] Furthermore, the discharge conveying group 502 includes a conveying motor 5021 installed on the conveying frame 4 by bolts, a second gear group 5022 rotatably installed between the conveying frames 4 and installed on the output shaft of the conveying motor 5021 through gear transmission, and a second chain belt 5023 installed between the conveying frames 4 through a rotating shaft. A chain transmission structure is installed between the first gear group 5011 and the second gear group 5022. The second gear group 5022 is driven to work by the conveying motor 5021 and the gear transmission structure. The second gear group 5022 drives the first gear group 5011 to work through the chain transmission structure, and then drives the first chain belt 5012 and the second chain belt 5023 to move to complete the conveying work.

[0044] Working principle: When in use, the conveying motor 5021 and the gear transmission structure drive the second gear set 5022 to work, and the second gear set 5022 drives the first gear set 5011 to work through the chain transmission structure, and then drives the first chain belt 5012 and the second chain belt 5023 to move, and the labeled bottles are placed on the second chain belt 5023 and enter the arc-shaped conveying channel 7. The through hole 8 is used to discharge the overturned bottles, and the bottles that are undergoing labeling inspection are sorted out, and the bottles are subjected to secondary inspection by the first photoelectric detection group 11. By adjusting the distance between the two spacing blocks 10, the bottles are sorted out. The walking trajectory of the bottle is arranged, and the straight conveying channel 14 between the side baffle 12 and the bottle blocking column 13 ensures the bottle walking trajectory, which is convenient for entering the rejection mechanism 2. The bottles with unqualified labels are rejected by the rejection mechanism 2. The specific working process has been described in detail in the comparative document and will not be described in detail here. The qualified bottles are detected by the second photoelectric detection group 6023 for the number of bottles. If the number per unit time is too large, the cylinder and the pushing block on the pushing member 6022 push the bottles into the sub-hopper 6024 to complete the diversion work and avoid the bottles from piling up at the discharge port. It is simple, convenient and practical.
